Tax Court Form 15 is the Application for Waiver of Filing Fee and Affidavit that lets low-income petitioners ask the United States Tax Court to waive the $60 petition filing fee when they cannot afford to pay it. You fill it out by stating your monthly income, listing your assets, listing your monthly expenses, and signing the affidavit under penalty of perjury, then filing it with your petition under Tax Court Rule 20(b).
The problem is simple. Most people who get a Notice of Deficiency from the IRS already feel squeezed by back taxes, penalties, and interest, and a $60 fee plus the fear of court can push them to give up their right to challenge the IRS before paying. According to the Taxpayer Advocate Service 2024 Annual Report to Congress, more than 25,000 petitions are filed in the U.S. Tax Court each year, and a meaningful share of self-represented filers qualify for fee relief but never request it because they do not know Form 15 exists.

What Tax Court Form 15 Actually Is
Tax Court Form 15 is a one-page sworn financial affidavit you submit to the U.S. Tax Court Clerk in Washington, D.C. when you cannot afford the $60 filing fee that normally accompanies a Tax Court petition. The form is authorized by Rule 20(b) of the Tax Court Rules of Practice and Procedure, which gives the Chief Judge discretion to waive the fee on a showing of inability to pay. The form became more important after the Taxpayer First Act of 2019 expanded access-to-justice protections for low-income taxpayers.
The plain-English meaning is this. If you swear under oath that you live on a tight budget and cannot spare $60 without skipping rent, food, or medicine, the Court has the power to let you file for free. The consequence of not filing Form 15 when you qualify is that your petition will be rejected if you also do not pay the fee, and missing the 90-day deadline to petition the Tax Court means you lose your right to challenge the IRS before paying the tax. A common misconception is that Form 15 is only for people on welfare. The form is available to anyone whose verified monthly expenses meet or exceed their income, including retirees, students, gig workers, and even small business owners with thin cash flow.
Imagine Maria, a 68-year-old widow in Tampa living on $1,420 a month in Social Security. The IRS sends her a $7,200 deficiency notice for a 1099-R she did not understand. Maria can use Form 15 to file her Tax Court petition without spending $60 she needs for her blood pressure medication.
Federal Rules Governing the Fee Waiver
Tax Court filing fees are set by 26 U.S.C. §7451, which caps the fee at $60 and gives the Court authority to waive it. The procedural rule that controls Form 15 is Tax Court Rule 20(b), which states the Court may waive the fee on application supported by an affidavit demonstrating inability to pay.
The plain-English explanation is that Congress lets the Tax Court charge a small fee to discourage frivolous filings, but Congress also told the Court not to lock the courthouse doors on people who cannot afford the price of admission. The consequence of ignoring this rule and submitting a petition with neither the $60 nor a Form 15 is a “notice of insufficient filing fee” from the Tax Court Clerk’s Office. The Court will give you a short window to pay or apply, and if you miss it after your 90-day petition deadline has passed, your case is dismissed for lack of jurisdiction.
A real-world example is Adkison v. Commissioner, where the Tax Court emphasized that strict jurisdictional deadlines apply even to indigent filers. The common misconception is that Form 15 also waives Tax Court session fees, copying fees, or transcript costs from the court reporter. It does not. Form 15 only waives the initial $60 petition filing fee.
How Rule 20(b) Differs From Federal Court IFP
In federal district court, indigent filers use 28 U.S.C. §1915, known as the in forma pauperis (IFP) statute. Tax Court fee waivers are similar in spirit but governed by a separate rule and a separate form. The Tax Court does not require a poverty-line calculation tied to the federal poverty guidelines published by the Department of Health and Human Services, but judges often look at those numbers as a benchmark.
The consequence of confusing the two systems is that filers sometimes attach a federal IFP form (AO 240) instead of Form 15, which slows the review or triggers a rejection. The example here is Daniel, a Phoenix mechanic who filed AO 240 by mistake. The Clerk’s office sent him a letter telling him to refile on Form 15, costing him two weeks of stress.
Where to Get Tax Court Form 15
The official Form 15 is hosted on the Tax Court website and you can download it directly from the forms library at ustaxcourt.gov. You can also pick up a paper copy at the Tax Court Clerk’s office at 400 Second Street NW, Washington, D.C. 20217. Low Income Taxpayer Clinics funded under IRC §7526 often supply the form for free along with help completing it.
The plain-English explanation is that you have three reliable sources: the website, the Clerk’s office, and an LITC. The consequence of using a third-party site that hosts an outdated PDF is that you may submit the wrong version, which can be rejected. A common misconception is that the form must be notarized. It does not need a notary because the affidavit at the bottom is signed under penalty of perjury under 28 U.S.C. §1746.
For example, Priya, a graduate student in Boston, downloaded Form 15 from an unofficial blog that had not been updated since 2018. The Clerk rejected the filing because the form layout was outdated. Priya then pulled the current PDF directly from the Tax Court site and refiled successfully.
Line-by-Line Walkthrough of Form 15
Form 15 looks short, but every line carries weight. Each entry is a sworn statement, and exaggeration or omission can lead to denial and, in extreme cases, perjury charges under 18 U.S.C. §1621.
Caption and Docket Information
The top of the form mirrors your Tax Court petition caption. You write your name as Petitioner, the Commissioner of Internal Revenue as Respondent, and leave the Docket Number blank if you have not received one yet. The Clerk will assign the docket number when the petition is filed.
The consequence of using a different name on Form 15 than on your petition is a mismatch that delays processing. A real example involves Robert, a retired teacher who signed his petition as “Bob Sullivan” and his Form 15 as “Robert J. Sullivan III.” The Clerk sent a request for clarification, costing him several weeks. The common misconception is that you must include your Social Security Number on the caption. You should never place your SSN on Form 15 or the petition because Tax Court Rule 27 requires redaction of personal identifiers.
Statement of Income
You list every source of monthly gross income, including wages, self-employment earnings, Social Security, SSI, SSDI, pensions, unemployment compensation, alimony, child support, rental income, investment income, and any cash gifts you receive on a regular basis. Use monthly figures, not annual.
The plain-English explanation is that the Court wants a snapshot of your real cash flow. The consequence of leaving out a recurring source like a $200 monthly side gig is that the IRS attorney may later subpoena your bank statements and challenge your affidavit. The example is Aisha, a part-time Lyft driver who forgot to include her $640 monthly rideshare income, prompting the IRS to oppose her waiver. The common misconception is that you only have to list “taxable” income. You must list all income, including nontaxable Social Security and gifts.
Statement of Assets
You list cash on hand, checking and savings balances, vehicles, real estate equity, retirement accounts, stocks, cryptocurrency, and any other property of value. Exclude ordinary household furnishings and clothing. The Court treats a homestead and one functional vehicle leniently if they are needed for daily living.
The consequence of inflating asset values or hiding a brokerage account is denial of the waiver and potential referral to the IRS Office of Chief Counsel for further investigation. The example is Marcus, a freelance graphic designer in Denver, who listed his 2012 Honda Civic at $1,800 and was approved. The misconception is that retirement accounts are excluded. You must list 401(k) and IRA balances, although the Court rarely counts them against you because of withdrawal penalties.
Statement of Monthly Expenses
You list rent or mortgage, utilities, food, transportation, insurance, medical expenses, child care, court-ordered support, and minimum debt payments. Be honest and detailed because the math must show your expenses meet or exceed your income.
The consequence of underreporting expenses, ironically, is denial because the numbers will not justify a waiver. The plain-English point is that this is the section where most pro se filers shortchange themselves. A common misconception is that “expenses” means luxury spending. The Court looks at necessary living expenses comparable to the IRS Collection Financial Standards used in Offer in Compromise cases.
Affidavit and Signature
The bottom of the form contains the affidavit declaring the contents true under penalty of perjury. You date and sign. If you are filing jointly with a spouse, both spouses must sign and both sets of finances must be reported.
The consequence of an unsigned Form 15 is automatic rejection. The example is Jennifer and Paul, married petitioners in Atlanta, who submitted the form with only Paul’s signature. The Clerk returned it. The misconception is that an electronic signature is acceptable for paper filers. If you mail the form, it must bear a wet-ink signature; only DAWSON e-filers may sign electronically.
Three Common Scenarios and Their Outcomes
Below are the three most popular Form 15 scenarios based on Tax Court statistics published in the Chief Judge’s annual reports.
Scenario Table 1: Retiree on Fixed Income
| Filing Move | Likely Result |
|---|---|
| Lists only Social Security as income and basic monthly expenses | Waiver granted under Rule 20(b) |
| Forgets to list a $400 monthly pension annuity | Waiver denied for incomplete affidavit |
| Lists $80,000 IRA balance with a note about 10% penalty | Waiver granted; Court treats IRA leniently |
| Refuses to disclose IRA at all | Waiver denied and possible perjury referral |
Scenario Table 2: Gig Worker With Irregular Income
| Filing Move | Likely Result |
|---|---|
| Averages 12 months of 1099 income honestly | Waiver granted if expenses match |
| Reports only “best month” of gig income | Waiver denied for misrepresentation |
| Lists business mileage and self-employment tax burden | Waiver granted with supporting math |
| Omits a side Etsy shop pulling $300 a month | Waiver denied if IRS discovers it |
Scenario Table 3: Small Business Owner
| Filing Move | Likely Result |
|---|---|
| Reports owner draw, not gross business receipts | Waiver granted when draw is below expenses |
| Reports business gross revenue as personal income | Waiver denied because numbers look inflated |
| Lists business debt obligations as monthly expense | Waiver granted if debts are personally guaranteed |
| Conceals an LLC checking account | Waiver denied and referred for review |
Three Named-Person Examples in Practice
Real examples show how Form 15 plays out in everyday filings handled through the Tax Court’s DAWSON system.
Maria, the Tampa Widow. Maria lives on $1,420 a month in Social Security. Her rent is $900, utilities run $180, food costs $300, and prescriptions take another $120. Her total expenses of $1,500 exceed her income by $80 a month. She lists a 2009 Toyota Corolla worth about $2,200 and $312 in a credit union savings account. Her Form 15 is approved within ten days, and she proceeds to challenge the deficiency without paying the $60 fee.
Daniel, the Phoenix Mechanic. Daniel earns $2,800 a month as a self-employed mechanic. After listing rent of $1,250, child support of $600, car insurance of $190, food of $500, tool loan payments of $220, and self-employment tax setasides of $400, his expenses total $3,160. Daniel attaches a one-paragraph explanation of his 1099 income volatility. The Court grants his waiver based on the collection standards benchmark.
Priya, the Boston Graduate Student. Priya lives on a $2,100 monthly stipend with $1,750 rent in a shared apartment, $260 health insurance, $180 groceries, and $90 in subway costs. Her Form 15 lists $4,400 in a checking account and $61,000 in federal student loan debt. The Court grants the waiver, noting that student loans are a liability and the checking balance is below the threshold for denial.
Mistakes to Avoid on Form 15
Even careful filers slip on details. Below are the seven most common errors that lead to denial or delay, drawn from filings tracked in DAWSON public dockets.
- Omitting nontaxable income such as Social Security, SSI, or VA benefits, which the Court treats as income for waiver purposes
- Forgetting to sign or date the affidavit, which causes an automatic Clerk’s rejection
- Including a Social Security Number in violation of Tax Court Rule 27 on redaction
- Underreporting monthly expenses, which paradoxically makes you look too solvent to qualify
- Using an outdated PDF of Form 15 from a third-party site instead of the official Tax Court forms page
- Filing Form 15 without an accompanying Form 2 petition, which the Clerk will not process alone
- Forgetting to attach the Notice of Deficiency, which is required by Tax Court Rule 34 to anchor jurisdiction
Do’s and Don’ts of Filing Form 15
The Tax Court evaluates each waiver on its own facts, but a few habits consistently help or hurt your application.
Do’s:
- Do download the current Form 15 directly from the Tax Court forms library so you use the latest version
- Do file Form 15 at the same time as your petition under Rule 20(b) so the Clerk processes both together
- Do list all income sources, including cash gifts, because honesty preserves credibility
- Do match your monthly expense categories to the IRS Collection Financial Standards to anchor your numbers
- Do consider free help from a Low Income Taxpayer Clinic listed on the Taxpayer Advocate website
Don’ts:
- Don’t notarize the form because the affidavit relies on 28 U.S.C. §1746 unsworn declarations
- Don’t include your Social Security Number anywhere, since Tax Court Rule 27 bans personal identifiers
- Don’t underreport rent or medical bills because honest expenses are what justify the waiver
- Don’t hide a retirement account because DAWSON’s public docket means IRS counsel can scrutinize your filings
- Don’t wait until day 89 of the 90-day petition window since postal delays can be fatal under IRC §6213
Pros and Cons of Filing Form 15
The waiver is helpful, but it is not free of trade-offs.
Pros:
- Saves the $60 filing fee for taxpayers who genuinely cannot afford it
- Protects the constitutional right to pre-payment review of an IRS deficiency under IRC §6213
- Signals to the Court that you are organized and credible, which helps in small tax case (S case) proceedings
- Can be paired with pro bono help from LITCs for a no-cost path to court
- Allows you to focus your limited dollars on substantive litigation rather than filing fees
Cons:
- Requires sworn disclosure of personal finances that becomes part of the public DAWSON docket unless sealed
- Adds an extra processing step that can delay docketing by a week or two
- Risks denial and a follow-up demand for the $60 if the affidavit looks incomplete
- Exposes filers to potential perjury liability under 18 U.S.C. §1621 for false statements
- Does not waive transcript, copying, or session fees charged later in litigation
Step-by-Step Process for Submission
The submission process follows a clear sequence from preparation to ruling.
Step 1: Gather Financial Documents
Pull together your last two pay stubs, last three months of bank statements, your most recent Social Security or pension benefit letter, your rent or mortgage statement, and your utility bills. These do not get filed, but they keep your numbers honest. The consequence of guessing is an affidavit that contradicts later discovery. A misconception is that you must attach the documents to Form 15. You do not; you keep them for your own records and produce them only if the Court asks. Daniel, the Phoenix mechanic, kept a spreadsheet of his bank deposits for six months, which he later showed the IRS attorney when she questioned his income.
Step 2: Complete Form 15
Fill in the caption, income, assets, expenses, and signature sections. Use a pen or type the form. The consequence of leaving any line blank instead of writing “$0” or “none” is a Clerk’s letter requesting clarification. A misconception is that you can attach a separate budget instead of completing the form. You cannot; the Court requires the official form. Priya, the Boston student, drafted her numbers in a spreadsheet first, then transferred them to the official PDF.
Step 3: File With Your Petition
Mail Form 15 with your Form 2 Petition, Form 4 Statement of Taxpayer Identification Number, and a copy of your Notice of Deficiency to the Clerk in Washington, D.C., or file electronically through DAWSON. The consequence of mailing without certified tracking is no proof of timely filing under the §7502 mailbox rule. A misconception is that DAWSON charges an extra fee. It does not.
Step 4: Wait for the Court’s Ruling
The Chief Judge or a delegated judge reviews the application and issues an order granting or denying the waiver, usually within two to four weeks. The consequence of denial is a deadline, often 30 days, to pay the $60 or your petition is dismissed. A misconception is that denial means your case is over. You can pay the fee and proceed normally. Maria, the Tampa widow, received her order in nine days and never paid a fee.
State Tax Tribunal Comparisons
State tax courts handle fee waivers differently, and the rules vary widely across jurisdictions.
| State Forum | Fee Waiver Mechanism |
|---|---|
| New York Division of Tax Appeals | No filing fee; no waiver form needed |
| California Office of Tax Appeals | No filing fee for taxpayer appeals |
| Illinois Independent Tax Tribunal | $500 fee with hardship waiver on motion |
| Minnesota Tax Court | $295 fee with IFP application available |
| New Jersey Tax Court | $50 fee waived for indigent filers under Rule 1:13-2 |
The plain-English explanation is that some states charge nothing, while others charge more than the federal Tax Court and use their own waiver procedures. The consequence of assuming the federal rule applies in state court is missing a payment deadline. The example is a New Jersey filer who used Form 15 in state tax court and had to refile on the state’s IFP application instead.
Recap of Relevant Tax Court Rulings
Several Tax Court orders shape how Form 15 is applied today, even though they are not always published as full opinions. In Adkison v. Commissioner, the Court reinforced that the 90-day petition deadline is jurisdictional, meaning a properly filed Form 15 cannot rescue a late petition. In Nutt v. Commissioner, the Court tightened the §7502 timely mailing rule for electronic filings, which matters when you e-file Form 15 through DAWSON.
The plain-English point is that fee waivers do not cure timing defects. The consequence of late filing is dismissal for lack of jurisdiction, even if Form 15 is perfect. A misconception is that the Court is lenient with pro se filers on deadlines. It is lenient on form, not on time. The example is a 2023 case where a self-represented taxpayer filed Form 15 on day 92, and the Court dismissed the case despite an otherwise valid waiver.
Key Entities Involved in Form 15
Several people, offices, and organizations shape your Form 15 experience, and knowing their roles helps you navigate the process.
The U.S. Tax Court is the federal court that hears pre-payment disputes between taxpayers and the IRS. The Chief Judge approves or denies your fee waiver under Rule 20(b). The Clerk of the Court is the gatekeeper who reviews your filing for completeness. The Commissioner of Internal Revenue is the named Respondent in every petition. The IRS Office of Chief Counsel represents the Commissioner in court. The Taxpayer Advocate Service advocates inside the IRS for taxpayer rights and funds LITCs that help low-income filers complete Form 15 at no cost.
Each entity has a distinct role. The Clerk does not decide your waiver; the judge does. The Taxpayer Advocate does not represent you in court; the LITC attorney does. Confusing these roles is a common pitfall for pro se filers.
